Mordekaiser Q
Morde lacks both mobility and utility. He also misses out on some strong items due to his lack of mana usage. I do not think he is a bad champion by any stretch because he makes up for these problems with his damage and defense as well as a generally amazing Ult. Given that his Q and his E are relatively similar moves I was wondering if Riot wouldn't mind doing something a little different with his Q. Maybe increased movement speed while Q is readied or add a CC effect on contact with an enemy? even if you didn't use the Q as a mobility or utility move it could stand to be something a little more interesting. he already has good poke and minion clear with his E and W, so maybe a buff or buff steal would be cool.
Just a thought!
